illustrates the best lorin in which .l have cony templared embodying iny invention and y said invention vl'uhy disclosed in the lollovfl ing description and elainis.

relerring to the drawing, rigore 1 represents a longitudinal 'ver ical sectional vieu' oll a WashingI machine having iny invention embodied therein. Fig. 2 is a transverse vertical sectional view ol' the saine.

ln the drawings 1 represents the exterior casing oi the inachine, which is pr Vlcrably cylindrical although it .inay be ol polygonal lorin in cross section. The casing 1 is supported on suitable E and is provided with a door 3, 'lor giving access to the interior. The casing l is also provided with an inlet pipe 4a and discharge pipo 11, having therein suitable cut-oil cocls 5'DL and 5 lor adinitting liquid to the interior ing it oft as desired. l also prel'er to provide the casing 1 with an overflow pipe lb as shown.

Within the casing 1 is a revoluble perlorated cylinder 6, here shown as provided at each oi' the ends with a plate 7 having a trunnion 8 projecting therel'roin and niountl ed in a bearing 9 in the adjacent end ol' the outer casing l. @ne ol the trunnions 3 is extended beyond the bearing 9 and provided with last and loose pulleys .10, 11, as shown, or other suitable ineans lor imparting rotary motion to the inner cylinder 6. rlhe inner cylinder or casing 6 is provided on the interior ol' its cylindrical portion with a plurality oi` ribs 12, extending entirely around the interior, each rib being in the i'orin oi' a continuous compound curve extending iirst on one side and then on the etaer side el' a inedian line. rllhe ribs 12 are prei'crably parallel to each other throughout, as shown and are ol' suchv height and spaced at such a unii'orrn distance apart as to engage o1 the casing and dravfl" if rique. when order to l l l i the carry up quantities of the clothes being treated and give theni a sidevsise bach and forth inoveincnt, through the the cylinderl is rotated. ln vvent the clothes lroin hailing or loria-ing into roll, .l inay provide the ribs .i2 at intervals 'with slight projections here shown in the l'orni el rounded knobs or studs lhese knobs er studs inay in seine instances be diin'iensed with. l also prefer to provide the cylinder 6 with boel/lets or other suitable devic to carrv up portions o1- the liouid ahoy the liquid level and disch it n sonic loi-ce upon the clothine' ln this stanco i have shown the interior el the Tlinde/r o pr 'ided adj ent to each end h a scf-ies ol' binaire/ts lornied by blades le "ing the adjacent end Wall, and the cylind. wall, said buckets icing so conim A) structed that they will carry up portions ol the liquid and discharge it upon the clothes above set l'orth.

The cylinders or casings 1 and 6 inay be niade ol either vvood or nietal as yrelUrred, and 'the inner casing` or cylinder G is provided with a plurality ol' perlorations 15, preferably located in the channels between the Waving ribs 12 and said inner cylinder is also provided with a door 16 which can be brought into substantial registration with the door S in the outer casing. The inner cylinder or casing 6 is operated continuously in one direction, to Wit, that indicated by the arrow in Fig. 2.

ln the operation of the device, the clothes to be treated are inserted in the inner cylinder 6 through doors 3 and 16, which are provided With suitable 'fastening devices, to secure thein in closed position and the cleansing liquid. is run into the outer casing through pipe e* and. Vlinds its Way through the apertures 15 into the inner casing. rllhe supply ol' liquid is then cut oli and power is applied to the inner casing to revolve it continuously in one direction. its it revolves the clothes will be inoved longitudinally of the cylinder E in both directions through the liquid, by the Waving ribs 12, which act similarly to a cani groove upon thein. d here the knobs or projections 13 are used, this action takes place between the said lnobs or projections, and the latter serve to turn the clothing and bring fresh portions thereof into contact with the Waving ribs, and the grooves formed between thein. is the cylinder 6 rotates the buckets fornied by the inclined blades 14 Will liquid at one side of the cylinder and pour or discharge it upon the clothes7 thus securing a circulation of the liquid and bringing all portions thereof into Contact With the clothing. The torce of the liquid striking the clothes also assists in removing the dirt therefrom.

What claim and desire to secure by Letters Patent is l. A Washing machine provided with a rotatable cylinder, having the interior of its cylindrical Wall provided With annularly arranged ribs and grooves alternating with each other, said ribs and grooves being each in the forni of a continuous compound curve, extending iirst on one side and then on thc other side of a inedian line.

2. washing machine provided with a rotatable cylinder, having the interior of its cylindrical Wall provided With annularlT arranged ribs and grooves alternating with each other, said ribs and grooves being each in the forni of a continuous compound curvo, extending iirst on one side and then on the other side of a median line, each ot said ribs being provided With a plurality of projec tions, located at intervals.

3. A Washing machine provided with a rotatable cylinder, having the interior of its cylindrical Wall provided with annularly arranged. ribs and grooves alternating With each other, said ribs and grooves being each in the forni of a continuons compound curve, extending lirst on one side and then on the other side of a median line, said cylinder being also provided with buckets for elevating portions oi the liquid contents and discharging it upon the clothing lying upon said ribbed and grooved portions.

l. in a Washing machine, the combination with an outer casing, of an inner cylinder rotatably mounted in said casing and having its walls perforated, and provided on the interior of its cylindrical Walls With annular Waving ribs alternating with similarly Waving grooves, said ribs being provided at intervals with inwardly projecting knobs, a series ot' buckets on the interior of said inner cylinder and means for rotating said inner cylinder continuously in one direction.

In testimony whereof aflix my signature7 in the presence of two Witnesses.
